Application August 5, 1947, Serial No. 766,140 I Claims. 1

My invention relates to an apparatus for disinfecting paper currency andhas for its principal object, to provide a simple, practical andinexpensive device designed for rapidly and effectively destroyingcontagious and infectious matter which may be carried by hand to handcirculated paper currency and which machine is particularly designed foruse in banking institutions, hotels, public markets, general stores,theatres, ball parks, or wherever there is an exchange of substantialamounts of paper currency.

With the foregoing and other objects in view, my invention consists incertain novel features of construction and arrangement of parts whichwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawing, in which:

Fig. 1 is a side elevational view of my improved paper currencydisinfector.

Fig. 2 is an enlarged cross section taken on the line 22 of Fig. 1.

Fig. 3 is an enlarged detail section taken on the line 33 of Fig. 2.

Fig. 4 is a fragmentary plan view showing the means for driving theendless flexible belt used in the machine.

Fig. 5 is a plan view similar to Fig. 4 and showing a modified form ofthe endless belt driving means.

Referring by numerals to the accompanying drawing, which illustrates apreferred embodiment of my invention, l0 designates a fiat topped tableor plate supported by legs I I, and mounted for rotation in bearings I 2on the ends of said table are the trunnions l3, of drums or rollers M.

The upper flight of an endless belt-like member I5, traverses the flatupper surface of table I0, said belt being composed of one or morelayers of fabric, more or less porous and preferably having a nap suchas plush or velvet, so as to receive and hold finely pulverizeddisinfectant.

This belt is carried by the drums or rollers, l4 and to operate same,one of the trunnions l3 carries on its outer end a crank handle l6, asseen in Fig. 4, or a manually operable disc such as IT, seen in Fig. 5.Arms 18 are disposed alongside table If], near one end thereof, and theends of said arms adjacent the end of the table are pivoted to studs |8aon the sides of said table.

Transversely disposed on top of table I0 is a hollow roller l9 having athin wall in which are formed perforations 20. One end of said roller isclosed by a disc 2! having a trunnion 22 and the other end is closed bya plug 23 having a trunnion 24.

Trunnions 22 and 24 are journalled in the free ends of arms l8 andretractile springs 25 connect the upper inner portions of arms l8, withthe sides of table Ill near one ,end, thus maintaining roller l9 inyielding contact with the endless belt 15, or the paper currency carriedthereby.

Trunnion 22, which is somewhat longer than trunnion 24, carries near itsouter end, inside arm IS, a loosely mounted disc 26, and positioned onsaid trunnion between disc 2| and disc 26, is a cylindrical plug 21, ofsponge rubber. In some instances, an expansive spring may be used in theplace of rubber plug 21.

Perforated roller [9 contains a loose metal rod or roller 28 which,during rotation of said roller I9, rotates in the lower portion thereof,thus tending to provide a forcible feed of the pulverized disinfectantthroughaperture 20 in roller l9, and also functioning as a stirrer forthe pulverized material.

In operation, the currency to be disinfected is laid fiat on the endlessbelt IE to either side of roller l9 and by means of crank IS, the beltis driven so as to carry the currency beneath roller l9, and thus thedisinfectant is simultaneously applied to both faces of the currency bysaid roller and belt. By driving belt l5 across the table several timesbefore beginning the disinfecting operations on a considerable number ofbills, the loading of the belt with disinfectin material is insured Inorder to refill roller [9 with pulverized disinfectant from time totime, said roller is forcibly moved lengthwise toward elastic plug 21,thus compressing same and enabling trunnion 24 to be disengaged from itsbearing in arm I8 and thereby permit the removal of plug 23.

Thus it will be seen that I have provided a paper currency disinfectingdevice that is simple in structure, inexpensive of manufacture and veryeffective in performing the functions for which it is intended.

Minor changes in the size, form and construction of the various parts ofmy improved paper currency disinfector may be made and substituted forthose herein shown and described, without departing from the spirit ofthe invention, the scope of which is set forth in the appended claims.

While my improved device is particularly designed for use indisinfecting paper currency, it is to be understood that it may beemployed with equal advantage in disinfecting coins, tokens used inbusiness, playing cards, hat and coat room checks, in fact anyrelatively thin articles which are handled and rehandled by the public.

I claim as my invention:

1. In a paper currency disinfector, a table, rolling supports on theends of said table, an endless belt mounted on said rolling supportswith its upper flight traversing the top of said table, a hollowperforated roller disposed transversely on the top'surface of the upperflight of said belt, and. means,,connecting said table and roller forcausing the latter to exert yielding pressure against the upper surfaceof the top flight of,

said belt.

2. A paper currency disinfector as set forth in claim 1, with a gravitymember loosely arranged within said perforated roller. I

3. A paper currency disinfector, 'as set forth in claim 1, with aremovable plug closing onevend of said roller.
